The array object itself provides many methods for operations on the object itself. join is one of the methods.

ObjArray. join (seperator)
Use the character specified by seperator as the separator to convert the array into a string. When seperator is a comma, it serves the same purpose as toString.

For example, if we have a string "a", "B", and "c", we want to output it in a, B, and c format, then we can:
Var a = ["a", "B", "c"];
Document. write ();
If join is used, it must be as follows:
Var a = ["a", "B", "c"]. join (",");
Document. write ();
If you say that you want to directly output abc without outputting a, B, and c, it is not appropriate to use join.
Var a = ["a", "B", "c"]. join ("");
Document. write ();
